The outdoor antenna receives and transmits signal to nearby cellphone towers. Outdoor antennas can be either directional or omni-directional.

2 – CELLULAR AMPLIFIER

The amplifier (or “repeater”) boosts the signal coming to and from and going to the cell phone tower. The “gain” of the amplifier describes how strong the amplification is – you’ll see that word scattered across our product pages.

3 – INDOOR ANTENNA

The indoor antenna rebroadcasts the signal inside the building. Some kits have more than one indoor antenna to help distribute the signal.
